WILLIAM VAN ANDEN,4 OF POUGHKEEPSIE, NEW YORK.

Letters Patent No. 85,347, dated December 29, 1868;

` IMIPROVED RAILWAY-RAIL CHAIR.

The Schedule referred to in these Letters Patent and making part of .the same.

.To all whomjit may concern:

Be it known that I, WILLIAMVAN ANDEN, of

Poughkeepsie, in the county of Dutchess, and State- It consists in providing a chair having corner bearingflanges with a perforated projecting base between them, by means of which great additional width and stiifness is obtained, and the chairs are thus prevented from rocking and cutting into the cross-ties on which they re placed. I t is designed to be an improvement upon the folded-lip chair, havingiall its advantages without its disadvantages.

To enable those skilled Vin the art to which my invention.appertains tomake and use the same, I will proceed to describe more fully its construction.

Figure l is a perspective view ofthe chair, and

Figure 2, a sectional View across the centre.

I first take a wrought-iron plate, A, of suitable size and thickness, and slit or cut it upon -each edge, near the ends ofthe plate, so that the' corners c c are formed,

the cut being made further in towards the centre-upon its upper side than upon its lower, as'is shown in iig. l. "lhat portion of the metal which occupies the centre space between the slits is then formed, by a swaging process, into a hooked ange, which bends towards the centre ofthe plate, as is shown in the iigures.

Instead, however, of simply turning up the metal in the centre, as is the case in the folded-lip chair, I forni a base, J', by the swaging process, which serves, with the bearing-anges 'c c, to give great stiffness to the chair when it is in position.

The line from l-Z, in iig. l, shows the greatest thicknessof the lip in the ordinary' chair.

The remaining portion J, it will be seen, gives a bearing-surface at the point where it is most needed.

e e represent spike-holes, which are found in the lips and base, so that the bearing-flanges are left uncut. The position of these may, of course, be varied to suit the rail.

By this construction, a wrought-iron chair is formed,

with the grain of the metal running in the proper direction to resist the strain, as is shown by the lines in iig. l, and a1 largely-increased bearing-surface is obtained in the same size f chair.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Patent of the United States, is-

The chair A, constructed as described, and having the bearing-flanges c c, inclined sides J J and perforations e c, all constructed and arranged as and for the purpose described.
